It doesn’t matter whether or not Indonesia recognized dual citizenship. What matters is that the United States does and did recognize dual citizenship.
Can you not read? The United States did not recognize dual citizenship until TEN years ago. When Obama was born the US did not recognize it. That is direct from the US Government site. Canada only recognized dual citizenship 20 years ago. In Indonesia you had to renounce your citizenship and only be Indonesian to attend their schools.
Excuse me but you conveniently ignored the part about traveling to Pakistan on something other then a US passport in 1981 when he was 20.
Indonesia and Kenya still do not recognize a dual citizenship.
You ever thought of researching before posting?
Berg's argument is that Indonesia required her to renounce her US citizenship in order to become an Indonesian citizen, and that because Barack was a minor, his status followed hers.
I have no idea if he is accurate on this.
